3.5.4 100 V slave input

The power amplifiers have a 100 V slave input (18) that

can be connected to an existing 100 V loudspeaker line.

In this way it is easy to connect an additional power

amplifier on a remote location for more output power.

The 100 V input is not affected by the control terminals

for input 1 priority (20) or input 2 enable (19).

Note

If the 100 V slave input is used, and the 0 V and

100 V are incorrectly connected, no pilot tone is

detected on the power amplifier. Refer to

section 4.1 for information.
